A rational equation is an equation in which one or more terms is a rational expression – a fraction in which the numerator and/or the denominator are polynomials. When solving a rational equation, a method known as cross multiplication is used to eliminate the denominators on both sides of the equation. For instance, using cross multiplication, we can rewrite the equation (3/x) = (6/x+4) as 3(x+4) = 6x, and then solve for x.
